Reliable Infrastructure, Careful Regulatory Compliance Protect Our Community

To provide high quality drinking water and recycled water for irrigation, DSRSD complies with the Safe Drinking Water Act and all other state and federal regulations. This requires managing the quality of water sources, employing state-of-the-art water purification processes, paying close attention to facility operations and maintenance, and conducting rigorous water-quality testing.

To collect, treat and dispose of the community’s wastewater, the District complies with the federal Clean Water Act and other regulations that protect public health and the environment. The DSRSD sanitary sewer system is designed and maintained to keep wastewater safely in the pipes and, at a minimum, meet state sanitary sewer overflow (SSO) regulations. In addition, DSRSD reaches out to treatment plant neighbors to understand their concerns and address impacts such as odor, architectural aesthetics, traffic, noise, and lighting.

DSRSD prepares to protect public health and the environment in emergencies, such as severe storms, when wastewater flows increase, and natural disasters, when pipelines may fail.
